OILER FOR ELEVATOR GUIDE-RAILS.

Patented March 23, 1909.

Serial No. 436,574.

To all whom t may concern;

Be it known that I, EDWARD I. PEARsoN, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Oilers for Elevator Guide-Rails, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use thesame.

This invention relates to lubricator'or oiling devices, and the object thereof is to provide an improved device of this class designed to be connected with an elevator car on the line 2-2 of Fig. 1, Fig. 3 `a vertical section on the line 3-3 of Fig. 2, Fig. l a side view of a detail of the invention, part of the construction being iny section, and;- Fig. 5 a plan view of the main casing `of my improved lubricator on a reduced scale.

In the drawing forming part of this specification, I have shown at a a partof the top of an ordinary elevator car, and at l) one of the guide rails which in practice are placed at the sides of the car. The elevator car is provided with the usual top cross head a2 with which is connected a guideshoe c which is movable on the guide rail t in the usual manner, and it will be understood that while only one of the guide shoes cis shown, one of these shoes is used in connection with each of the guide rails. I also provide a lubricator or lubricating or oiling device d which is connected with a support e secured to the top frame work or cross head 0.2 of the car, and in practice one of these lubricating or oiling devices is employed in connection with each of the `guide rails.

In the construction of my improved lubricating device I provide acasing d2, a plan view of which is given in Fig. 5, and this casing is preferably rectangular in cross section and is provided in one side with a vertical recess d3 in which the guide rail l) or the inwardly directed web b2 thereof is movable. The casing d2 is provided with two side chambers or portions d4 formed by the vertically arranged recess da and in each of which is placed a yoke-shaped frame f comprising parallel side members f2 connected by a cross head bottom portion f3, and in the bottom of each of the yoke-shaped-framesf is mounted a roller f4 provided with trunnions f5 which pass through and are movable in vertically arranged slots or openings f6 in the sides f2 of the frames f and connected with the ends of the trunnionsf5 are plungers g movable in casings gr2 on the sides f2 of the yoke-shaped frames f, and in which are placed springs g3 which normally serve to depress the plungers g and the rollers f4.

' In the tops of the side portions f2 of the frames f are mounted rollers 71. having trunnions h2 on which are mounted side links h3, and in which are mounted rollers i having felt or other fibrous coverings i2, and the rollers t are provided with trunnions which pass throu h the links 71,3, and at the inner ends of sai rollers are placed felt washers L* adjacent to which are washers h5 preferably composed of fiber and adjacent to which are placed washers `h" preferably composed of metal, and' between the Washers h6 and the corresponding links h3 are placed spiral springs k7 whichnormally serve to force the rollers i outwardly into the position shown in Fig. 2,'and the top portions of the links 71,3 are connected at the inner sides of the frames f bya spiral spring 72,8, and these springs cause the rollers i to bear on the web b2 of the guide railb.

The frames f do not come entirely to the top `of the'casing cl2V of the lubricating device, the relative positionl of the tops of said frames being shown atv f 7 in Fig. 3, and the top walls of the recess d3 in the outer side of the casing d2 are lower than the other top Wallsof said casing, as shownat d5 in Fig. 3, and the rollers 'i are so placed or supported that theyl normally rest inwardly of and above the rollers h and bear on the web b2 of the rail bias clearly shown in Figs. 2 and 3.

The rollers h are provided centrally with an annular groove j, and mounted on the rollers f4 and h in each of the frames f is a fibrous belt or band jz, and the outer surfaces of the band i2 are flush with the surfaces of the roller he IOO In practice the casing d2 is partially filled with suitable lubricating oil as shown at o in Fig. 8, and the rollers f4 are always covered With this oil, and the endless belts or bands y'z Which are preferably composed of fibrous material carry this oil up to and supply it to the rollers i or to the fibrous covering of these rollers, the said rollers t' or the fibrous covering thereof and the rollers 7i being normally in contact.

As the elevator moves up and down in the operation thereof, the rollers lz' constantl bear on the opposite sides of the web b2 of the rail b, and the opposite sides of said web are thusY kept constantly lubricated at all times. In this operation the washers h4 are also lubricated and the inner face of the Web b2 of the rail b is lubricated by said Washer.

The casing d2 of the lubricating device is providedwith a cover lc having a slot or opening Win one side thereof which correspends with the recess d3 in the casing d and through which the web b2 of the rail l) is movable, and said cover lc is provided, in the form of construction shown, with doWel pins 7c3 adapted to enter corresponding recesses in the top of the casing d2, and the top portion of said casing is also provided With springs lc4 which bear on the cover lc When it is placed in position and normally hold it in place on the casing d2. y

It Will be observed that the outer trunnions of the rollers 7L pass through the outer Walls of the casing d2 and are provided with nuts m, and this construction holds the frames f in proper position at all times, and the said nuts may be detached when necessary and the frames may be moved inwardly and removed from the casing (Z2 Whenever desired for cleansing, repair or other purposes.

The casing cl2 is provided at its inner side with a boss a with which is connected a threaded arm n2 Which is mounted in or secured to the support e, and this forms a support for the casing d2, but my invention is not limited to any particular means for supporting the lubricating device over the elevator car, and any suitable device or devices may be employed for this purpose. My invention is also not limited to the particular construction of the rollers i, the rollers 7i or the rollers f4, vnor to the material used therein, or in the belts f2, and any suitable material may be used in the construction of said rollers and belts, and various other changes in and modifications of the construction herein described may be made, Within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

With my improvement the amount of oil or lubricating material applied to the guide rails is just suicient to accomplish the desired result, and there is no Waste or leakage,

and no surplus oil or other lubricating material collects on the guide rail.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
